Lookleft,
I know exactly what I wrote, and stand by it. That you are not able to comprehend is your problem, not mine.
Lead Balloon is quite correct, of course, in general the Commonwealth has the power to administer ALMOST all of civil aviation via S 51 of the Constitution. But not ALL of it, and the most interventionist state is Queensland. Most (all) states maintain certain commercial aviation licensing powers, quite separate to the Commonwealth.
I know well what the dam case was all about, a confirmation of the power conferred by the treaty making powers under the Constitution, if you can't work out how that possibly impacts aviation,(or many other fields where the Commonwealth and an international treaty is involved) I can't help you.
Tootle pip!!
